1. INTRODUCTION
This instruction sheet covers assembling a terminated
contact, housing and TPA as represented in Figure 1
and extracting the contacts from the housing.
Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.
NOTE
Dimensions in these instructions are in metric units [with
inches in brackets]. Figures and illustrations are for
reference only and are not drawn to scale.
2. DESCRIPTION
All VAL-U-LOK pin and socket contacts have two
flexible latches that lock into their respective housings
when fully inserted. The TPA-compatible contacts
have special features on their insulation barrels that
work in conjunction with the TPA device to ensure full
contact insertion. See Figure 2A.
The plug and receptacle housings are available in 2
through 24 positions which are arranged into 2 rows.
The TPA devices are available in 1 through 12
positions, single row, so 2 TPA devices are required
for each housing. The TPA is designed to be installed
into the housing to ensure all contacts are fully
inserted and will not back out during mating. When
fully installed, the locking latches of the TPA snap onto
raised ledges around the perimeter of the housing.
See Figure 3B.
3. ASSEMBLY
1. Ensure that the contact is properly terminated to
the wire according to the requirements provided in
Application Specification 114-13172. Check that the
flexible latches are not damaged or distorted from
their original form as shown in Figure 2A.
2. Insert the terminated contact into its respective
housing as follows:
a. Grasp the contact directly behind the
insulation barrel. Align the contact with a contact
cavity in the housing at the wire entry end as
shown in Figure 2A. Make sure that the contact is
perfectly aligned (not angled or rotated) to the
contact cavity. See Figure 2B.
